Product Introduction
Momentive SNAPSIL™ RTV112 is a one-component, self-leveling silicone adhesive sealant ideal for applications requiring flow into narrow voids, crevices, and hard-to-reach areas. It cures at room temperature when exposed to moisture, forming a tough and resilient silicone rubber. RTV112 is widely used for electrical insulation, thin-section potting, and protective coatings. Its excellent weatherability, ozone resistance, and thermal stability make it suitable for a wide range of industrial environments.
